Invert split domain configuration or stop it

Hi all,

we've set up a split domain configuration between Lotus Domino system and Zimbra system. This has let us the time necesary for the migration of all the users' accounts.

Now, we're getting close to the end of the migration process, but this means we're going to migrate the most important part of users. In order to avoid creating accounts on Domino that redirects to Zimbra accounts (this is done in order to permit Zimbra users and Domino users to communicate the simpliest way), I need to invert the split domain configuration.

At the end of the migration, a Domino server will serve as an archives server, so I'll need to end the split domain configuration.

Can you tell me how to invert and stop the split domain configuration (no information in the wiki) ?
